                    .pb-3 In bi-directional mode, content is first pulled from the storage target. Any newer content overwrites local content. New content since last sync is then pushed to the storage target, overwriting any content on target if present.
                    strong Push to target #[em.red--text.text--lighten-2(v-if='tgt.supportedModes.indexOf(`push`) < 0') Unsupported]
                    .pb-3 Content is always pushed to the storage target, overwriting any existing content. This is safest choice for backup scenarios.
                    strong Pull from target #[em.red--text.text--lighten-2(v-if='tgt.supportedModes.indexOf(`pull`) < 0') Unsupported]
                    .pb-3 Content is always pulled from the storage target, overwriting any local content which already exists. This choice is usually reserved for single-use content import. Caution with this option as any local content will always be overwritten!
